Answer:
multiply the ratio of quantities by 100%
Step-by-step explanation:
You usually explain a process by describing how it is done. The ratio of two quantities is expressed as a percentage by multiplying that ratio by 100%.
<u>Example</u>
A as a percentage of B is (A/B)×100%.
_____
You will often see a description of finding a percentage as involving multiplication by 100. What multiplication by 100 does is give you a quantity 100 times as large. Generally, that will not be the number you are looking for.
For example, <em>one out of four</em> as a percentage is not (1/4)·100 = 25. 25 is two tens plus 5, a number way larger than 1/4. Rather, it is (1/4)·100% = 25%.
"Percent" and "hundredths" are interchangeable. The percent symbol (%) is a shorthand way to write /100, which is what it means. Consider the above example:
25% = 25/100 = 1/4 . . . . these are all the same value, written differently
In decimal, ...
25% = 25/100 = 0.25 . . . . these are all the same value, written differently
Take 30% of all the numbers from colors and add up
Answer: Yes, it would be biased. If David asked the question about movies, however, it would not be.
Step-by-step explanation: It would be biased because he is asking listeners to his show who send fan mail. Fan mail is typically only sent by people who enjoy the creator. Therefor, he would be surveying only people who enjoy his podcast so the results would be heavily biased. I am unsure about how the second part of the question relates to the first part. If David were to ask the same 100 individuals about their favorite movies rather than whether or not they liked his podcast, it would not contain biased results because he or his podcast does not have anything to do with movies. :)
Given a regular 20-gon ( a 20 sided polygon )
The measure of each interior angle will be given by:

where n is the number of sides
Substitute with n = 20
So, the measure of each interior angle =

The sum of exterior angles = 360
So, the measure of each exterior angle = 360/20 = 18
